News: Sierra was outrighted to Triple-A Omaha on Wednesday.
Impact: Sierra will be removed from the 40-man roster as a result, but will stick in the organization as a depth outfielder. The 26-year-old logged 161 mostly unimpressive at-bats between the Blue Jays and White Sox last season, batting .230 with two homers.

News: Sierra was designated for assignment by the Royals on Tuesday.
Impact: Sierra was removed from the 40-man roster to open up a spot for Kendrys Morales. He hit well after the All-Star break last season, so he could garner some interest on the waiver wire.
